Strong Experience in the Injection Molding Industry

In 1966 three friends, B.L. Jacquet, L.L. “Mack” McKay Jr., and J.F. Cox, came together with their TW-3ideas, experience and drive to form JMC Plastics and Manufacturing. The company initially operated out of the garage of McKay’s home. As the business grew, JMC relocated to its current location in north Houston. Mack McKay later bought out his partners and continued to expand the company through the years, purchasing adjacent land to grow the business and adding machinery. Upon his death in 2003, Mack’s nephew, Randy Hammond, took over as president of JMC and ran the company until his passing in 2012. The McKay family sold the business to the Robertson family, also of Houston, in 2013 and the company was renamed RMC Plastics, Inc. The company carries on the traditions and mandates of its founders: to produce the highest quality products possible at the very best value.
